FIELD: drawing samples of high-viscosity asphalt-resinous oil and petroleum products from different levels in reservoir, tanks cars and other reservoirs and storages. SUBSTANCE: proposed sampler includes cylinder with carrying rope; lower hole of cylindrical housing has polished surface tightly faying to taper surface of bottom. Taper bottom of sampler is not connected with cylindrical housing; it is made in form of weight which is rhomboid in cross section whose mass is no less than 3 kg. Upper surface of this weight tightly fays to lower hole of cylinder at contact with cylindrical housing. Lower part of weight is made in form of pointed cone for easy penetration into viscous mass of oil or petroleum products. EFFECT: enhanced efficiency. 3 cl, 2 dwg
